TIIVIE CNTROLUNG DANlPER MEl-llltllllll SPECIFIGATION forming part of Letters Patent No. 733,515, dated February 28, 1905.

Application filed January 23, 1904. Serial No. 190,345.

To f//ZZ wir/0792, it may concern:

Bc it known that I, 'IInnnunrlnren How aLl. GALLowAY, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful improvements in Time Controlling' Damper llflechanism, of which the following is a specification.

My invention relates to improvements in furnace-draft-regulating devices; and the object of the invention is to devise a simple automatic device whereby the draft-damper of -furnaces may be opened and the check-damper closed at a predetermined time, thereby regulating to a nicety the temperature of a house without the necessity of personal attention at inconvenient periods, as is required at the present time; and it consists, essentially. of a box provided at one endV with an alarirnelock, a lever pivoted in the opposite end of the box and having the long end extendingl inwardly and connected to the bottom of the box by a link extending slightly over the end, said link being connected by a weighted cord to the alarm-hammer of the clock and a cord detachably connected to the .short end of the lever outside of the box and having a weight suspended therefrom, such cord extending and being operatively connected to the draft-dani- 'per, check-damiiier, and slde-dampers, the parts being otherwise arranged and constructed in detail as hereinafter more particularly explained.

Figure .l is a perspective view showing a furnace provided with my equipment. Fig. 2 is an enlarged detail of the operating portion of the equipment.

ln the drawings like characters of reference indicate corresponding parts in each ligure.

A is the furnace. which is provided with the usual bottom draft-damper B, shown closed, the top eliecledainper C, shown open. and the slide-damper D, shown closed, as indicated.

E is a box suitably supported in the wall of the furnace-room or basement and provided with a transparent front c suitably hinged, so that it may be readily opened.

F is the alarm-clock, located in the bo.' at one end and having' the alarm-bell removed therefrom.

fis the vibrating hammer of the alarm-bell.

G is the leverextendingthrough the opposite end of the box to that in which the alarmbell is located and pivotcd on a bracket y.

y' is a ringl suspended by a chain or cord y and through which the leverbrextcnds. rlh-o ring y is designed to limit the downwaul movement of the lever G.

The lever (l is preferably provided with a reduced end g, and gf* is a link connected at one end to the staple at the bottom of the box andthe other looped end being arranged to extend over the reduced end ,//3 of the lever.

2 is a flexible cord which connects the link y! with the hammer l? of the alarm-clock. (ln the cordll provide, preferably. a ring-weight 3, so as to always keep the llexible cord 2 taut.

H is a cord provided with a ring 71, which is designed to extend over the short end of the lever G, and H' is a weight which is suspended from the cord l-l and designed to exert an upward ln'essure tothe long end, so as to hold the Lipper end of the link securely yet delicately on the extreme reduced end of the lever. The cord Il hangs loosely from a puls leyT YlV on the ceiling and extends over such pulley, through another pulley, l', thence to the lower end of the damper ll. l providea hook on the lcord for a purpose which will hereinafter appear. and a hook l connect lthrough one of the links j of the cord J,

which cord extends over a pulley j on the Yceiling and around a pulloyjl", secured on a standard j to the slide-damper l A branch cord H2 is connected to the cord l-lv below the pulley lf and extends over one sheaf of the double pulley K down to a weight 1C, to which it is securely fastened, thence over the sheaf 1:' of the double pulley li, to and over the pulley L, attached tothe ceiling, and down to the cheek-damper C. The cord H is provided with a loop /rfi for a purpose which will hereinafter appear.

The operation of my device is as follows:

' rlhe alarm-clock is first set 'in the usual way so as to ring at a certain hour in the morning' or at any other convenient period. As soon as the first tremor of the hammer starts the link g4 is drawn 0H the end of the lever G, and thereby the lever is tilted on its pivot, so as to drop the iing L, and consequently the weight H, which pulls down upon the cord H and raises the damper B. The cord H2 at the same time pulls the weight K upwardly toward the sheaf of the pulley K, and the cord H2 passing over the sheaf r consequently slackens between the pulley K and the furnace, thus allowing the check-damper to fall. It will be seen that the draft will now be on in full force without any check and that the furnace will burn up briskly. The advantage in this of course will be readily understood to those having to get up early in the morning to attend to the furnace, and especially from the fact that early rising is obviated and the house will be warmed thoroughly before the inmates get u p. It will therefore be seen that the furnace may be banked up at night and the rooms kept cool for sleeping, which is an important desideratum. Should it be desired at any time to allow thc furnace to burn up for a predetermined length of time, this may also be cffected by removing the cord H from the damper B and connecting' the hook i to the eye 7b2 in the cord H2, in which case the damp/er C would close the same as the damper B, so that immediately the weight Hl falls the damper C would likewise be opened and the draft checked. It will also be understood that where slide-dampers are provided, as indicated at D in the drawings, such slide-dampers may be manipulated simultaneously with the main damper by reason of the connection of the cord J to the main cord H by the hook j extending into one of the links. The amount of movement of the slide-damper may be varied as may be required, depending' upon the position that the hook occupies in the links j.

It will be seen from this description that I provide a very simple device, which is not liable to get out of order, for controlling the draft and check dampers of a furnace, which requires but a minimum amount of personal attention. ln this specification also it will be seen that I provide a weight on the cord, and this is important, for the reason that it holds the cord always taut and ready for immediate action.

That I claim as my invention is- 1. In a furnace-draft-regulating device, the combination with a suitable clock having a vi brating member, of a lever suitably pivoted, a link connecting the long end of the lever to a rigid support, a flexible cord connecting such link to the vibrating member, and a cord suspended from the short end of the lever and provided with a weight and extending over suitable guiding pulleys or ways to the damper Aas and'for the purpose specified.
